Further, the hook portions of the first and second vertical plates 122 and 123 face in opposite directions to each other, respectively. The hook portions of the first and second standing plates 122 and 123 face in opposite directions to each other in the width direction of the rail 200, respectively. The hook portions of the third and fourth standing plates 124 and 125 face in opposite directions to each other, respectively. The hook portions of the third and fourth standing plates 124 and 125 face in opposite directions to each other in the width direction of the rail 200. This allows the support bracket 120 to be located between two rail beams and below the chassis of the vehicle.

In order to ensure the stability of the supporting frame 120, as shown in fig. 2, the supporting frame 120 further includes a stabilizer 129, and the stabilizer 129 is connected to the two vertical plates 121. The stabilizer bar 129 is connected to two vertical plates 121 at two ends of the support frame 120 along the length direction. The stabilizer bar 129 and the riser 121 may be connected together by a connector such as a bolt.

The stabilizer bars 129 are spaced apart from the main beams 126 in the height direction of the support frame 120. The stabilizer bar 129 and the main beam 126 are respectively located at both ends of the vertical plate 121 along the height direction of the support frame 120. The stabilizer 129 is connected to a top end of the vertical plate 121 in the height direction of the support frame 120. The main beam 126 is connected to the bottom end of the vertical plate 121 along the height direction of the support frame 120. The stabilizer bar 129 is closer to the hook 127 than the main beam 126 in the height direction of the support frame 120. Therefore, the two ends of the two vertical plates 121 in the height direction of the support frame 120 are connected with the main beam 126 through the stabilizer bar 129, and the stability of the support frame 120 is improved.

As shown in fig. 4, the support frame 120 includes two stabilizer bars 129, and the two stabilizer bars 129 (a first stabilizer bar 130 and a second stabilizer bar 131) are spaced apart in the width direction of the support frame 120. Both ends of the first stabilizer bar 130 in the length direction of the supporting bracket 120 are connected to the first vertical plate 122 and the second vertical plate 123, respectively. One end of the first stabilizer bar 130 along the length direction of the supporting frame 120 is connected to the top end of the first vertical plate 122. The other end of the first stabilizer bar 130 along the length direction of the supporting frame 120 is connected to the top end of the second vertical plate 123.

Both ends of the second stabilizer bar 131 in the length direction of the supporting bracket 120 are connected to the third vertical plate 124 and the fourth vertical plate 125, respectively. One end of the second stabilizer bar 131 in the length direction of the support frame 120 is connected to the top end of the third vertical plate 124. The other end of the second stabilizer bar 131 along the length direction of the supporting frame 120 is connected to the top end of the fourth vertical plate 125. Therefore, the main beam 126, the four vertical plates 121 and the two stabilizer bars 129 can jointly form a hexahedral frame structure, and stability is good.

Further, as shown in fig. 2, the lifting member 111 is located between the stabilizer bar 129 and the main beam 126 in the height direction of the support frame 120. The lifting member 111 carries the downward force which is transmitted through the main beam 126 to the two risers 121. The stabilizer bar 129 can connect the tops of the two vertical plates 121, so that the stabilizer bar 129 can support the two vertical plates 121, prevent the two vertical plates 121 from moving toward each other, and prevent the main beam 126 from deforming.

The lifting member 111 has a receiving groove 132, and the receiving groove 132 is opened toward the stabilizer bar 129. The opening direction of the receiving groove 132 is toward the stabilizer bar 129 in the height direction of the support bracket 120. The receiving groove 132 is used to support a portion of the chassis. A portion of the chassis can be located below the second surface 206 of the track beam in the height direction of the support bracket 120. For example, the chassis has a guide bar located below the second surface 206 of the rail beam in the height direction of the support frame 120.

The first and second stabilizer bars 130 and 131 are spaced apart in the width direction of the support bracket 120. A portion of the chassis can extend through the gap between the first stabilizer bar 130 and the second stabilizer bar 131. A portion of the chassis can extend into the receiving groove 132 in the height direction of the support frame 120 so that the receiving groove 132 supports the chassis, so that a supporting force upward in the height direction of the support frame 120 can be applied to the chassis, and thus the vehicle can be raised so that the wheels move upward to be spaced apart from the rail beam.

The lifting assembly 110 includes two lifting members 111, and the two lifting members 111 (a first lifting member 112 and a second lifting member 113) are spaced apart along a length of the main beam 126. The first lifting member 112 has a first receiving groove 133, and the second lifting member 113 has a second receiving groove 134. The opening directions of the first receiving groove 133 and the second receiving groove 134 are both toward the direction of the chassis. A part of the chassis can be commonly supported by the first receiving groove 133 and the second receiving groove 134, thereby improving the stability of lifting and preventing the vehicle from being inclined.

The lifting assembly 110 can lift the locked wheels off the surface of the track beam without damaging the track beam and form a space for the lifting vehicle 140 to construct.

The specific structure of the lift truck 140 will be described below.

The lift truck 140 can roll on the rail beam instead of a locked wheel. As shown in fig. 2, the lift truck 140 includes a moving assembly 150, and the moving assembly 150 is used for moving the wheels. The moving assembly 150 includes a connecting member 151, a rolling member 156, and a carriage member 159, each of the rolling member 156 and the carriage member 159 being connected to the connecting member 151.

The connection member 151 may be configured as a substantially block-shaped structure. The rolling members 156 may be configured as rollers. The rolling members 156 may be connected to the connecting member 151 by an axle. The axle may be detachably connected to the connection member 151 by a nut. The rolling members 156 are able to rotate relative to the axle. The rolling members 156 are rotatable about the axial direction of the axle. The axial direction of the wheel axle is vertical to the length direction of the track beam. The outer peripheral surface of the rolling member 156 is in contact with the second surface 206 of the rail beam. The rolling members 156 are able to roll on the rail beam. The rolling members 156 are movable along the length of the rail beam.

The carriage member 159 is spaced from the rolling members 156 to avoid the carriage member 159 interfering with the rolling of the rolling members 156. The trailer member 159 is used to support the wheels. When the wheels are raised upwardly and spaced from the rail beam, a trailer member 159 is located between the wheels and the rail beam to support the wheels. The carriage member 159 is rotatable relative to the connecting member 151 to wrap around the outer peripheral surface 205 of the wheel. The rolling members 156 can move on the rail beam instead of the locked wheels, thereby moving the vehicle, and thus causing the broken vehicle to move away. Thus, the rolling members 156 can move the carriage member 159 in the longitudinal direction of the track beam, thereby moving the wheels.

Specifically, as shown in fig. 3, the moving assembly 150 includes two connecting members 151, and the two connecting members 151 (a first connecting member 152 and a second connecting member 153) are arranged at intervals.

The first rotating shaft 162 rotates about the axial direction of the first rotating shaft 162. The first rotating shaft 162 can rotate the first arc-shaped plate 164, so that the first arc-shaped plate 164 can be attached to the outer circumferential surface 205 of the wheel.
